COMPLETE MILLING TECHNOLOGIES OF DIFFERENT VALUABLE MATERIALS

摘要

In different technological processes, despite their peculiarity, there always arises one and the same matter - basic materials reducing to inner and external transformation with which to gain expected results. Milling of materials is one of the main technological processes beside thermal treatment, pressure or sub-pressure processes and fractionation. To provide the next stages of technology, the milling is essential because it provides, usually, a prerequisite for physical, chemical and thermo-chemical basic processes. If it's needed to reduce particles during the technological process, in this paper is given information how to select grinding equipment and the type of grinding that can treat particles to medium fineness needed, as well as factors to consider when selecting equipment.
